Book Description
A new genus, Varioonops, is established for a group of species characterized by sexual dimorphism in abdomen morphology (with a dorsal scutum present in males but not females), male palps with a separate cymbium and bulb, and a patterned abdomen. The closest relatives of the new genus appear to be three similar, but as yet undescribed, Neotropical genera that share those characters, but the members of Varioonops are united by a putative synapomorphy that does not seem to occur in those undescribed groups: a granulated sternum. Attention is drawn to the cymbial cone, a structure (possibly a receptor) found near the tip of the cymbium in Varioonops, members of the Orchestininae, and at least some soft-bodied members of the Oonopinae. A total of 23 new species are described: V. cafista (the type species), V. velsala, V. montesta, V. spatharum, V. poas, V. varablanca, V. tortuguero, V. veragua, V. heredia, and V. girven from Costa Rica, V. ramila and V. sansidro from Costa Rica and Panama, V. funator and V. cerrado from Panama, V. edvardi and V. sinesama from Colombia, and V. yacambu, V. trujillo, V. pittieri, V. chordio, V. parlata, V. potaguo, and V. grancho from Venezuela.

Book Description
Two new genera, Ponsoonops and Bipoonops, are established for groups of species characterized by sexually dimorphic dorsal abdominal scutum expression (with a scutum present in males but not females), male palps with a separate cymbium and bulb, and a patterned abdomen. Both genera belong therefore to the Varioonops complex, represented now by three described Neotropical genera. Members of Ponsoonops are united by three putative synapomorphies in males: a "pierlike" dorsal scutum completely fused to the epigastric scutum, a patch of short setae ventrodistally on metatarsi I and II, and a short anteromedian protrusion on the endites. Female Ponsoonops specimens differ from other members of the Varioonops complex in having small lateral sclerites at the epigynal area and a smooth sternum. Members of Bipoonops share a large, irregularly shaped, rather indistinct dark spot posteriorly on the carapace, a putative synapomorphy, and a moderately rugose sternum surface; males are characterized by a distinct, bipartite conductor. A total of 22 Ponsoonops species, 21 new to science, are described: P. duenas, P. hamus, and P. tacana from Mexico, Guatemala, and Belize, P. bilzi, P. lucha, P. samadam, P. sanvito, and P. viejo from Costa Rica, P. bollo, P. boquete, P. coiba, P. fanselix, P. frio, P. lerida, P. mirante, P. panto, P. salimsa, and P. vuena from Panama, P. pansedro from Colombia, P. micans (Simon, transferred from Dysderoides) from Venezuela, P. yumuri from Cuba, and P. lavega from the Dominican Republic. Bipoonops is described for three new species found on the western slope of the Andes in Ecuador: B. baobab, B. pucuna, and B. tsachila.
